A unsophisticated and low noise playback is the "job" of a good phono preamplifier. With the PHO-500 we managed this. The reason for is in the first step a complex drafted power supply, which is built in an external housing and in the second step the careful choosen components. Besides you can make individual adjustments by DIP-switches on the PHO-500.
